Trakio vs G

Trakio — GPS Lap Timer for Track Days Trakio is a focused lap timing app built for drivers who want clean data and zero distraction on track day. Open the app, select your circuit, and drive — Trakio handles the rest. Pre-Session Checklist Before you head out, Trakio confirms you're ready: GPS signal strength, battery level, and start/finish line configuration. No surprises on your out lap. Auto Circuit Detection Trakio uses your location to automatically identify your nearest circuit and pre-select it for you. Check the weather conditions and wind at the track, then name your session and go. GPS Lap Timing Laps are timed automatically as you cross the start/finish line — no buttons to press while driving. Run it on your iPhone's GPS, or pair a Bluetooth receiver for a faster, sharper data stream. External GPS Support Connect a Qstarz BL-1000GT / BL-818GT or a RaceBox Mini, Mini S or Micro, and Trakio times your laps from a 10-25Hz stream instead of the roughly 1Hz your phone provides. Crossings land where you actually crossed and sector splits hold up. Circuits Around the World Search in English or Japanese, filter by country, sort by what's nearest, and star the ones you run most. Every circuit is drawn with its real outline, so you know a track by its shape. Session Analytics After each session, dive into your data: - Best lap time - Top speed - Lap consistency score - Theoretical best lap (your best sectors combined) - Lap delta trend — see if you were improving or fading - Full lap-by-lap breakdown with gap to your best GPS Trace on Satellite Map Each session shows your smoothed GPS line overlaid on a satellite map of the circuit, with start/finish and sector lines marked. Session History Your session history is stored on-device. Search and filter by all sessions, recent, or your best runs. Rename sessions, log your car, add notes, and track your progress across every visit to every circuit. Global Leaderboard Optional, and entirely up to you. Post a lap to the leaderboard for a circuit and see where it lands against other drivers. Nothing is published unless you choose to share it. Share Your Results Share your session highlights as an Instagram Story — choose a template, add a background photo, and post your best lap straight from the app. Trakio Pro Trakio is free to try with 3 saved sessions. Trakio Pro unlocks unlimited saved sessions, PDF lap time sheets, and CSV lap exports. Available as a yearly auto-renewing subscription or a one-time lifetime purchase. The yearly plan renews automatically unless canceled at least 24 hours before renewal, and is managed in your App Store account. Payment is charged to your Apple Account. Designed for the Track - Dark mode for early morning sessions - Available in English and Japanese - No account required — sessions, laps and notes stay on your device. Only a leaderboard time you choose to share leaves it. Circuit outlines are derived from OpenStreetMap data, © OpenStreetMap contributors, ODbL 1.0.

WHERE YOU LOSE TIME — A G-BOX SIGNATURE FEATURE Open a lap and G-Box shows on the map which corners cost you time and how many tenths. No digging through telemetry graphs: it's fully automatic, right on your iPhone. Works with G-Box recordings and sessions from RaceChrono, AiM, MoTeC, TraqMate or Race Navigator. The benchmark is your own car on your own tires: the best pass through each corner from that car's fast laps (within 3.5% of the best) on the same track that day — not someone else's record. Tap a marker for the cause in plain words (braking too early, a slow exit) and what to do on the next lap. "Compare with lap N" puts the faster lap on the graph and map in one tap. Created by a professional racing driver and instructor. VIDEO WORTH SHARING Record with iPhone cameras or connect a GoPro. G-Box overlays lap time, speed, G-forces, track map and RPM on your video. Pick a race-car style dash or a vertical layout for social media. On supported iPhones, film both cameras at once: the road and the driver. ALL ON ONE IPHONE 25 Hz Fusion combines the iPhone's GPS and motion sensors to calculate a smooth driving line between GPS fixes, with no external receiver. These are calculated positions, not 25 Hz satellite measurements; results depend on GPS reception and phone mounting. Add a compatible OBD adapter, such as OBDLink MX+, for RPM, estimated gear and power, or an external GPS receiver: G-Box, RaceBox Mini, Mini S and Micro, and selected Dragy models. COMPARE YOUR LAPS • Automatic lap timing, live delta, sectors and predicted lap time • Every corner in one table: this lap, the day's best pass and the difference in braking, turn-in, apex and exit speed • Speed, G-forces, RPM and delta on synchronized graphs and map, against any lap from any session on the same track • Friction Circle and a theoretical best lap from your strongest sectors • Car class from power-to-weight and tire grip: performance points, SPORT to GT4, and leaderboards by track • Session replay on 2D and 3D maps YOUR DATA, YOUR WAY Import sessions from RaceChrono, Harry's LapTimer, VBOX, Race Navigator, MoTeC, AiM and TraqMate. Export to GBO, CSV, VBO, GPX and NMEA. TRY IT BEFORE YOUR TRACK DAY Open the included Nürburgring Nordschleife demo lap (8:06) to explore maps, graphs and lap timing before your first session. YOUR FIRST TRACK DAY WITH PRO Your first 3 sessions with laps are recorded with full G-Box Pro and stay unlocked for good: where you lose time, video, overlays and lap comparison. Sessions without laps don't count. FREE AND PRO Free: lap timing with iPhone GPS, map and speed graph, session import, OBD logging, and a preview of the analysis: how much time you could gain and in which corners. G-Box Pro: the full analysis with time lost per corner, causes and tips, 25 Hz Fusion, video recording and overlays, lap comparison, all telemetry channels, OBD power and external GPS receivers. Pro is a one-time purchase, not a subscription, and includes 1,000 credits for AI analysis. More AI credits are available in separate packs. Location access is required for GPS lap timing. For closed race tracks only. Set up your phone before driving and never operate it while driving. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
